To @ZZ whom t may concern:

Be it known that I, BENJAMIN G. DEvon, a citizen of the United States,residing at Lima, in the county of Allen and State of Ohio, haveinvented certain new and useful Improvements in Oil-Burners; and Idodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in hydrocarbon-oil burners foruse in heating and cooking stoves, furnaces, tbc.

The object of the invention is to provide a burner of this characterwhich shall be simple, cheap, anddurable in construction, efficient inoperation, which is composed of aA minimum number of parts, which maybereadily taken apart for cleansing and repairs, and which dispenses withthe use of pipes and other parts which are liable to become clogged byresiduum or injuriously affected by a high degree of heat.

With this and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be hereinafter more fully described, and particularly pointedout in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of aportion of a cooking stove or range, showing the application of theinvention thereto. Fig. 2 is a vertical longitudinal section of thesame. Fig. 3 is a top plan View of the burner removed from the stove.Fig. 4 is a longitudinal section through the burner on a larger scalethan in Fig. 2. Fig. 5 is a cross-section through the combustion-chamberon line 5 of Fig. 4. Fig. 6 is a top plan Viewof the burner with thehood and the cover of the combustion-chamber removed. Fig. 7 is aperspective View of the burner base and frame, and Fig. 8 is a rearelevation of the draft-door.

Referring now more particularly to the drawings, the numeral ldesignatesacookiugstove of any ordinary or preferred construction, the same beingprovided With aire-box 2 and with a hearth or shelf 3 at one endthereof, which shelf is arranged at the base of a draft-opening formedin the end Wall of the stove. This opening is ordinarily closed by ahinged door, which isopened and closed to increase and decreasethedraft, as desired. In carrying my invention into practice Isubstitute for the ordinary form of door a door 4, which closes only theupper portion of the `draftopenin, .3;, leaving a space below ofsuiiicient size to receive the burner, which projects into the fire-boxof the stove. The door 4t is hinged at one end in the usual manner bythe rod or pintle 5 to the wall of the stove and is provided with a slotor recess at its opposite side to Aengage a catch 6 on the stove,whereby said door may be held closed. At each side the door is providedwith downwardly-projecting legs 7, which are adapted to seal or closethe spaces between the wall of the stove and the end walls 0f the burnerto prevent the escape of heat or the access of air to the stove exceptthrough the proper channel. The upper portion of the door is formed orprovided with a longitudinal series of perforations 8, regulated by asliding valve or damper 9, havinga finger-piece 10 projecting to theexterior, whereby it may be adj usted to close said openings to stop thedraft or to open them to any desired extent to ad mit a greater or lesssupply of air to the stove to support combustion, as desired.

The `burner comprises in its construction a base-frame 11, `consistingof a front base or su pportin g plate 12, a trough or pan 13, whichforms the body or bottom section of the co1nbustion-chamber, and sidewalls 14, which are enlarged at 15 between the plate 12 and front wallof said pan 13. The said front wall 16 of the pau 13 is curved upwardlyand forwardly above the plane of the rear wall there of and connectswith the enlargements 15 of the sides 14..

Supported by the plate 12 is an oil pan or reservoir 17,which isremovable and is of such size as to it snugly'between the front-ends ofthe sides 14 and to bear against the front sur-A face of the wall 16.This oil-pan forms the fire-box of the burner and is supplied with oilfrom a supply-pipe 18, having a feed-valve 19, preferably of globe form,which may be regulated to feed the oil to the pan in quantitiescorresponding to the amount required for consumption to produce a givendegree of heat.y A wick 20, of asbestos or other suitable material, maybe placed in'theoil-pan, if desired.

The upper rear portion of the oil-pan is closed by a segment-shaped hoodor deflector 21, which projects downwardly a short distance into the panand fits snugly between the side walls of said pan to form a channelregulating the supply of air through the open space at the front of thepan to the space beneath said hood or deflector and thence to thecombastion-chamber, hereinafter described. The trough or pan 13 isclosed at top by a removable cover-section 22 to form acombustionchamber through which the heat and flames from the fire-boxcirculate before passing into the fire-box of the stove. Thiscombustionchamber is divided to form upper and lower iiues or passages23 and 24 by a horizontal partition-plate 25, which has a front wall 26,

i curving upwardly and forwardly between the curved front wall 16 of thetrough V13 and the correspondingly upwardly curved wall 27 of the cover22, thus forming an inlet to said lower passage 24 and an outlet fromthe upper passage 23 to the interior of thestove. This outlet may or maynot be provided with a slide or damper for controlling the draft, asdesired. The hood 21 is provided at its rear edge with a rounded rib 2S,which is adapted to t within a corresponding groove or recess 29, formedin the said front edge of the front wall 26 of the partition-plate 25,whereby said hood is supported in position and is allowed to have alimited hinge action to provide for the insertion and removal of theoil-pan 17 in the manner hereinafter described. The two passages 23 and24 of the combustion-chamber are in communication at the rear end of theburner through aslot or passage 30,formed in the partition 25. The uppersurface of the trough 13, the under surface of the cover 22, and bothsides or surfaces of the partition 25 are formed with longitudinal ribsor projections 3l, the ribs or projections upon the partition beingarranged to come on lines between the partitions of the bottom trough ofthe combustion-chamber and the cover-section thereof, so as to formaseries of flues or passages for the circulation of the flames andproducts of combustion from the oil-pan and lire-box 17 and to providealso additional surfaces for the storage up of heat to place theunconsumed products of combustion into the best possible condition forcomplete or practically complete consumption. The cover 22 is held inposition by a bolt or key 32, passed through the bottom wall of thetrough 13, the partition 25, and through said cover, and having at itslower end a head to bear against the bottom of the trough and formed atits upper end with an openingforthe reception of a pin or key 33 toretain said bolt in position and prevent displacement of the cover,while the partition is provided around its side and rear edges with aflange 34, which bears against 'the outer surfaces of the side and rearwalls of the bottom section 13 of the combustionchamber and retains saidpartition against displacement. It will thus be seen that the parts ofthe burner are few in number, detachably connected in a simple andeective manner, so as to be readily disconnectible for cleaning orrepairs, and that but one fastening device-nam ely, the pin or bolt32-is employed, this, unlike bolts and nuts or other fastenings, beingreadily and conveniently removable and easily replaceable when burnedout, warped, or otherwise rendered useless by the action of heat.

As clearly shown in Figs. 1 and 2, the burner is supported within thefire-box of the stove and projects to the exterior through the space oropening in the base portion of the door 4, so that the oil-pan 17 isexposed upon the exterior for the ready feed of oil thereto from thesupply-pipe 1S and for its convenient insertion and removal for cleaningor repairs. It will be seen that the legs 7 of the door 4 rest incontact with beads or strips 34 upon the side pieces of theburner-frame, so as to close all inlets or crevices at these pointsto-prevent interference with the proper draft through the opening 8,controlled by the sliding damper 9.

In operation oil from the supply-pipe 18 is fed through the globe-valve19 into the oilpan 17 and is ignited, the flames, smoke, and products ofcombustion, together with the air drawn in through the open front topportion of the pan 20, passing to the rear beneath the hood 21 andthence through the passage 24 to the rearof the base of thecombustion-chamber, thence up through the slot or ,opening 30 into thepassage 23, and ont into the fire-box of the stove through the outletbetween the curved front walls of the cover 22 and partition 25. In thuspassing through the combustion-chamber the flames are brought intocontact with the partition 25, which forms a flame-plate and heats saidpartition to a white heat, whereby the heavy hydrocarbon vapor and smokyflames after having been oxygenated by the air entering the oil-pan andfire box are brought'into direct contact with an incandescent surfaceand entirely consumed, producing a llame of intense heat. I am therebyenabled to burn crude oil without the objectionable hissing noiseordinarily produced and with little or no loss of combustible elements.

By simply tilting the forward end of the oil-pan 17 upwardly and pullingit outwardly said pan may be readily and quickly removed for cleaningpurposes without disturbing'the hood 21, and after cleaning the pan maybe restored to its orginal position by inclining or tilting it in themanner stated and forcing it under the hood, which yields to allow it toassume its proper position.

The great advantage of my burner herein described is that it is composedof comparatively few parts, which may be readily assembled anddisassembled, and in dispensing with the use of pipes and other similarparts, which are liable under the intense heat to warp, carbonize, or tobecome otherwise in- IOC IIC

juriously affected, thus rendering the burner uncertain in action and iexpensive to construct and to maintain in repair.

By simply removing the door 4: the burner may be drawn out and the partsof the combustion-chamber disassembled for the cleaning out of anydeposit or residuum of burned oil and also for convenience forrepairing.

The burner is adapted for use in cooking and heating stoves of variouskinds and for various types of furnaces without materially altering theconstruction or departing from the essential features of the invention.

Having thus fully described my invention, whatI claim as new, and desireto secure by Letters Patent, is-

1. A hydrocarbon-oil burner having a combustion-chamber subdivided by aflame-plate forming bottom and top inlet and outlet passages incommunication at one end of the chamber, an oil-receptacle incommunication with the inlet-passage at the other end of the chamber,and a hood guarding said inletopening and partially overhanging saidreceptacle for regulating the inner draft of air through the saidinlet-passage, substantially as and for the purpose set forth.

2. A hydrocarbon-oil burner comprising a base having a trough formingthe lower portion of a combustiowchambeiga cover closing the trough andforming the upper portion. of the combustion-chamber, `a partitionsubdividing said chamber to form upper and;` lower passages incommunication at one end and provided, respectively, at the other endwith an inlet and outlet, anoil-pan resting upon the base adjacent tosaid inlet, and a hood or dellector for conducting the indrawn`munication at one end of the chamber and having their inlet and outletopenings located at the opposite end of the chamber, an oilreservoir,and a hood partially overhanging the oil-reservoir for conducting theair and products of combustion therefrom Vto the inletopening of `saidinlet -passage, substan` tially as and for the purpose specified.

4. A hydrocarbon-oil burner comprising a base having a trough formingthe lowerpor-A tion of a combustion-chamber, a covericlosa ing thetrough and forming the upper portion of the combustion-chamber, and apartition forming a flame -plate and separating-said lower and upperportions of the chamber to form inlet and outlet passages, said passagesbeing in communication at one end of .the chamber and having their inletand `outlet openingsat the opposite end of the chamber, substantially asdescribed.

In testimony whereof Ihave hereunto set my hand in presence of twosubscribing Wit; l
